C 1 1. Connect a 10 p. pi tubular ceramic capa-
citor from lug 1 of coil CE (NS) to lug 7 of
tube socket V4 (S-2).
Connect a very short length of stripped
hookup wire from lug 1 of coil CE (S-2)
to lug 3 of tube socket V4 (S-1). Be sure
that it
does not short to lug 2 of V4.
Mount the oscillator coil (#40-186) CF.
Connect a 3" length of hookup wire from
lug 2 of coil CD (NS) to lug 2 of coil CF
(NS).
Connect a 4-3/4" length of hookup wire
from lug 2 of coil CD (S-4) to lug 2 of
switch Z (S-2).
C4. Connect a .001 mid disc ceramic ca-
pacitor from lug 2 of coil CF (NS) to the
ground lug nearest lug 8 of tube socket V5
(S-1).
R2. Connect a 22 102 (red -red -orange) 1
watt resistor from lug 2 crystal socket
M (S-2) to lug 2 of coil CF (NS).
C5. Connect a 10 µpi tubular ceramic ca-
pacitor between lugs 1 (NS) and 2 (S-4) of
coil CF.
Connect a length of stripped hookup wire
from lug 1 of coil CF (S-2) to lug 9 of tube
socket V5 (NS).
C6. Connect a 50 1.01f silver mica capacitor
between lugs 2
(S-2) and 9 (S-2) of tube
socket V5.
Connect a length of heavy bare wire from
lug 1 of coil CD (S-1) to lug 3 of tube socket
V5 (S-2).
C7. Connect a .001 p.fd disc ceramic capa-
citor from lug 4 of tube socket V5 (S-2) to
the center post of V5 (NS).
C2. Connect a .001 pid disc ceramic capa-
citor from lug 5 (5-2) to the center lug of
V5 (S-4).
) Install the .001 !Ad feed -through capacitor
T. Use the nut furnished with the capacitor.
Do not overtighten this capacitor since you
may crack the insulating material. See
Detail 4B.

(
) Now, cut the lead extending from the top of
the feed -through capacitor flush with the top
of the insulating material. See Detail 4B.
(
) Cut the lead extending from the bottom of
the feed -through capacitor to 1/4" as shown
in Detail 4B.
(
) Connect a 2-1/2" wire from lug 4 of termi-
nal strip S (S-3) to feed -through capacitor
T (NS).
(
) Prepare the final tank coil (#40-335)
and
trimmer capacitor C16 as shown in De-
tail 4C.
